COLEOPTERA. 401 



Plectes and Cec/iemts *, founded on the relative proportions of the 

 head and thorax. The nature of the surface of tlie elytra furnishes 

 the other secondary characters of these divisions, and such was the 

 method of Messrs. Clairville and Bonclli. 



The greater number of these species inhabit Europe, Caucasus, 

 Siberia, Asia Minor, Syria, and the north of Africa to the thirtieth 

 degree of north latitude. Some few are also found at the two extre- 

 mities of America, and it is probable that others may be found in 

 the intermediate mountains (a). 



Of those with a convex and oblong body, the most common 

 is the C. auratus, L. ; Panz. Faun, Insect. Germ., LXXXI, 4, 

 commonly called the Jardinier. It is about an inch long, golden 

 green above, black vmderneath; the first joints of the antennae 

 and the legs fulvous; elytra sulcated, unidentated on the exterior 

 margin near their extremity, particularly in the female, Avith 

 three smooth ribs on each. 



This Insect disappears in the south of Europe, or is only 

 foimd there in the mountains \. 



Those are most generally furnished with wings. Their mandi- 

 bles are transversely striated, and without any visible teeth on the 

 internal side. The thorax is transversal, dilated equally, rounded 

 laterally, and without any prolongation at the posterior angles. The 

 abdomen is almost square. Their exterior palpi are less dilated at 

 the extremity. The maxillae are suddenly curved at the extremity.

IX^ (a) Of the species that inhabit North America, we have as yet only discovered 

 the C. Beauvoisi, carinatus, Lherminier ? Unealopitnclaids {sirratus, Say), rin([ sylcosus 

 and vinctvs. The mountains of New Hampshire, and Maine particularly, probably 

 contain several others, and it is to be hoped that some friend of the science, within 

 reach of those localities, •will soon enable us to enlarge our catalogue of this interest- 

 ing genus. — Eng. Ed.
